+%28x-2%29%5E3%2F4+=+8+
+%28x-2%29%5E3%2F4+=+2%5E3+
+%28+%28x-2%29%5E%281%2F4%29+%29%5E3+=+2%5E3+
Take the cube root of both sides
+%28+x-+2%29%5E%281%2F4%29+=+2+
Raise both sides to the 4th power
+x+-+2+=+16+
+x+=+18+
------------
check:
+%2818-2%29%5E3%2F4+=+8+
+16%5E%283%2F4%29+=+8+
+%28+16%5E%281%2F4%29+%29%5E3+=+8+
+2%5E3+=+8+
+8+=+8+
OK
